Specification of Letters P'aten't Patented May 18, 1909.

To all whomit may. concern: Be it known that I, GEORGE A. SEIB, citizen of the United States, and resident of Syracuse, in. the county of Onondaga and State of New York, have invented certain new and useful Improvements in Type- Writing Machines, of which the following is a specification.

My invention relates more especially to the paper feeding mechanism of typewriting machines and has for its chief object to ro-' vide an improved paper feeding device 0 the kind commonly known in the art as a paper fin er.

0 this and other ends my invention consists in the features of construction, combinations of devices and arrangements of parts hereinafter described and particularly point- In the accompanying drawings, Figure 1 is a vertical front-to-rear-sectional view of the upper portion of a typewriting machine and showing so much of the structure as is necessary to a clear understanding of my invention. Fig. 2 is a front elevation of the same, parts being omitted. Fig. 3 is a detail side elevation of the paper feeding device showing the feed or pressure roller in inoperative position. Figs. 4, 5, 6 and 7 are detail views of various parts of the aper feeding device.

My invention is s own as app ied to the f Monarch typewriter but it is to be understood that it may be adapted to other forms of writing machines. p

In the drawings, grooved guide rails 1 and 2 are secured to brackets 3 fixed to the top plate of the machine. Anti-friction balls 4 cooperate with the guide rails and also .with the grooved back bar 5 of a latch carrier which comprises, besides said ack bar, side bars 6 and 7 extendin forwardl therefrom and supporting a cyhndrical p aten 8. A paper table 9 is suitably secured to the platen; carrier and directs the paper a to a paper apron 10 supported in the carrier and formed with openings for the main paper feed rollers 11 which are diagrammatically shown in Fig. 1. Aplaten scale 12 is fixed to the forward ends of spring arms 13, the rear ends whereof are secured to the platen carrier. The side bars 6 and 7 of the platen carrier are provided with u wardly extending portions 14and 15 which are apertured to receive a rod or bar 16 which is suitably secured in place. The bar 16 extends longitudinally of the platen and is situated above the latter and slightly to the rear of its axis as best seen in Fig. 1. The parts thus far described generally resemble those found intheMon'arc'h machine.

v The bar 16 is provided with a longitudinal groove 17 and serves as a support for one or more .paper feeding devices or paper fingers designated as a Whole by. the reference number 18. The paper fingers comprise a carrier 19 for both the aper guide'and paper feed roll, a paper gui e 20 and a' paper feed .roll or pressure device 21. The carrier 19 comprises a hub portion 22 which embraces the rod. or bar 16, and anarm 23 integral with the hub 22 and extending forwardly over the platen. A U-shaped bar spring 24 is contained within thehub 22 and enters the groove 17 in the bar 16 as best seen in Fig. 4. The spring 24 is confined within the hub 22 of the carrier, the ends 25 of said spring engagin notches formed in the ends of said hub an reventing said spring from being displaced by accident. I The body or bar portion of the spring enters the groove 17 and presses against the bottom thereof with sufficient force to prevent accidental displacement of the carrier 19 longitudinally of the bar 16. The bar spring 24 is of sufficient width to fit snugly in the roove 17 r and prevent rotary movement of t e carrier which may be into ral with the body portion of said guide ut which is preferably made in a separate piece and secured to said body portion by rivets 28 as best shown in Fig. 6. The guide portion proper extends downwardly and forwardly, conforming to the surface of the platen and terminating near the top of the platen scale 12. The paper guide 20 is normally pressed against the platen by a coiled spring 29, one end of and serve in effect as a housin for said.

which abuts against the bottom of ti e paper guide between the ears 26 and theoil of which is received in a recess or depression 30 formed in the under side of the carrier arm 23. The ears 26 extend far enough forward of the pin 27 to conceal the spring 30 spring, the latter always being hi don from view. The spring 29, it will be noted, is arran ed wholly at one side of the dpivot of the guide 20 and is compressible an expansible 1n the direction of its own length.

The forward end of the carrier arm 23 is formed with faces 31 and 32 at right angles to each other, and fixed in said forward end is a pin 33 which serves as a pivot for the feed roll device 21, the latter comprising a body portion 34 formed with bifurcations 35 through which the pivot pin 33 freely passes,

said bifurcations embracing the end of the carrier arm 23 as best shown in Fig. 5. A

I short rod or spindle 36 is reduced and threaded at one end, said end being received in a tapped hole in the side of the body portion 34, and mounted to turn freely on the spindle 36 is a sleeve 38 which is kept in p ace by a headed screw 39 which screws into the other end of the spindle 36. The portion of the sleeve 38 farthest from the part 34 is provided with flanges 40 between which-a sheath or covering 41 of rubber-or the like is confined, the latter constituting a feed roll. Between the bifurcations or ears the body )ortion 34 of the feed roll device is provi ed with a recess or depression 42 which receives a coiled spring 43, the upper end whereof abuts against the bottom of a. plunger 44 and presses the head] 45 of said plunger against the end of the carrier arm 23. When the feed roll device is in normal or operative position the head of the plunger 45 engages with the face 32 at the end of the carrier arm, the arts being so related that the feed roll 41 is then pressed toward the platen through an opening 46 formed in the paper guide 20. WVhen it is desired to render the feed roll device inoperative, it is swung upward about its pivot until the head of the p unger disengages from the face 32 and is brought into contact with the face 31 of the carrier arm against which" paper fingers which cooperate with the paper near its opposite side edges, said paper fingers being adjustable toward and away from 'each other along the support or bar 16. It.

will be noted from an inspection of Fig. 2,

1er end said work sheet wherein both paper lingers are shown, that the hub portions 22, the pa er guides 20 and the feed roll devices'21 of t e two paper fingers are all off-set from the carrier arm 23 inwardly or toward the center of the machine so that the carrier arms may be moved'outwardly beyond the ends of the platen' and yet the paper fingers will still be in position to guide and control the paper.

The paper fingers are ad usted likewise of the support 16 until they are in position to 006 erate properly with the side edges of the wor sheet a whether the latter be in a form of paper, envelo s, .cards or the like, and sing introduced into the machine at .the back,. is guided over the paper table .9, thence passing between the platen and the main feed roll 11, the paper apron '10 and the scale 12. lmmedlately a or passing above the scale 12 the top edge of the work sheet asses into the-control of the lower ends of the paper fingers by which it is guided and fed upwardly and rearwardly over the support 16 and ,out of the machine.

The pa or guide and feed rolls are outside the print ng field of the work sheet or paper.

a, and cooperate with the margin thereof to guide and feed the work sheet overthe bar or support 16 so that there is no obstruction .to the o erators view of the writing as the sheet is ed beyond theprinting line.

It will be noted that the paper guides 20 are inde endently spring marginal 'feed rolls or rol ers 41 are independently spring pressed, and that said guides 20 are independent of each other as well as of their associate feed rollers, while the feed rollers are likewise independent of each other. This construction enables each paper guide and feedroller to cooperate with.

the work sheet independently so that any inequality in said work sheet encountered ressed, that the I guide 20; and furthermore the margin feed independently of their associate guides, the operator is enabled to release the paper sufficiently to effect its adjustment Without entirely freeing it from the control of the paper y my construction I provide a paper finger or paper feeding device which is simple in construction, efficient in operation and sightly in a pearance, the paper guide and the feed ro er which are mounted on said paper finger being pressed by springs which are concealed from the view of the operator.

It is to be understood, of course, that I do not desire to be limited to the precise construction shown and that various changes may be made within the scope of my invention;
